fixed problem that \fIfea_edit\fR had with files
containing CHAR generic header items.
.ip \fIfeafunc\fR
an additional function \fIexp10\fR
(ten-to-the-power, inverse of \fIlog10\fR) has been added.
.ip \fIfeafunc\fR
minor changes were made to specify explicitly the
value returned by
convention by LOG for zero arg.  This was done for the benefit of the new
function \fIarr_op\fR, which uses the LOG case of arr_func in computing powers.
.ip \fIfilter\fR
this program has been removed and replaced by \fIfilter2\fR, which was
introduced in the previous ESPS release.   \fIFilter\fR has been
removed (it is unstable) and the name \fIfilter\fR is now linked to
\fIfilter2\fR.
.ip \fIfind_ep\fR
bugs fixed: (1) the filename in the common file was not 
updated if the \fB-w\fR option was in effect;
(2) one of the debugging messages produced with the \fB-x\fR option showed
garbage for the output file name;
(3) if the \fB-n\fR option was used with no filename in common, the program
would produce a core dump, rather than an error message, before
exiting.
The 150 ms lower limit on "silence_req", the argument of the \fB-s\fR
option, is no longer enforced; it is just stated as a recommend lower
limit in the manual entry.
A missing \fB-b\fR option was added to the Synopsis in the manual entry.
.ip \fIimage\fR
a bug in the \fIimage\fR program was fixed that caused core
dumps when a
debug level of 2 or higher was specified with the \fB-x\fR option.
.ip \fImbuttons\fR
If \fB-c\fR is specified, a set of exclusive panel choice buttons is used
for each olwm submenu instead of a menu button with a pull-down menu.
By default the choice buttons are laid out vertically.  If \fB-h\fR is
used, they are laid out horizontally.
.ip \fImbuttons\fR
added \fB-Q\fR option to allow arbitrary label for
quit button; added \fB-l\fR option to allow command for execution on
exit via quit button.
.ip \fImu2esps\fR
this program can now handle SUNOS 4.1 audio file
headers.
.ip \fIplot3d\fR
Two \fIplot3d\fR bugs were fixed:  moving the box with the
mouse with no
data loaded could cause a core dump; sometimes the 3d cursors were
drawn in the wrong relation to the mouse position.   Major improvement
is that hardcopy output of the plot is now possible, in either
PostScript or PCL.   A print setup panel is available for selecting
output type, scaling, and output device.
.ip \fIplotfield\fR
A bug was fixed in the plotfield script that
caused incorrect processing
of command-line arguments when the text argument of the -t option
contained blanks.
.ip \fIsfconvert\fR
changed the default value of \fIsfwin_len\fR in
the default parameter file to a more reasonable value of .01 (seconds).
.ip \fIsgram\fR
reversed the sense of the \fB-z\fR option so that
warnings about zero power in frames are off by default.
.ip \fIsplay\fR
a bug was fixed with caused the \fB-a\fR to have no
effect unless the \fB-b\fR option was used also.  And if \fB-a\fR and
\fB-b\fR are both used, the \fB-b\fR option has no effect.
.ip \fIsrecord\fR
modified to require an output file, or \- to specify
standard output.
.ip \fItofspec\fR
The tofspec program can now produce FEA_SPEC files
in "ARB_FIXED" format---frequency values are not necessarily uniformly 
spaced and are given by an explicit list in the header.  The frequencies 
may be specified by a command-line option or a parameter-file entry.
.ip \fIvqasc\fR
memory leak fixed.
.ip \fIvqdesasc\fR
added \fB-l\fR option as was added to \fIvqasc\fR
in version 4.2.   This option is to allow specification of input line
length to override compiled in default.
.ip \fIwmse_filt\fR
a FIR design program by minimum mean square error criteria,
no longer prompts user for design parameters.  It now supports
standard ESPS parameter file processing, which can be used with
\fIxeparam\fR(1-ESPS), and \fIeparam(1-ESPS)\fR.
.ip \fIxfft\fR
\fIxfft\fR was changed to permit a \fB-c\fR option; a new parameter
file \fIPWfftc\fR was created to facilitate taking fft-spectrograms of
complex sampled data.
.sh 1 "NEW AND CHANGED LIBRARY FUNCTIONS"
.ip \fIarr_func\fR
modified to handle additional function,
\fIexp10\fR, inverse of \fIlog10\fR.  Use by \fIfeafunc\fR program.
.ip \fIarr_op\fR
This a new library function for performing
element-by-element arithmetic operations on arrays of any of the ESPS
numeric types.  The currently supported operations are addition,
subtraction, multiplication, division, forming a complex number from
its real and imaginary parts, and raising a given number to a given
power.
.ip \fIexv_bbox\fR
exv_bbox was extended to support exclusive
panel_choice buttons for submenus instead of menu buttons with pull-down menus.
There are two new items in the parameter structure (typedef bbox_par):
.nf
  int button_choice;            /* if true, show submenus as panel choice
                                   items instead of button menus */
  int choice_horizontal;        /* if true, panel choice items are
                                   displayed horizontally */
.fi
.ip \fIexv_bbox\fR 
added the following parameters for allowing the user to put
an arbitrary label on the QUIT button and to execute an
arbitrary function when it is pressed
.nf
          char *quit_label;     /* if non-NULL, name for QUIT button */
          char *quit_data;      /* QUIT button data string */
          void (*quit_data_proc)(); /* execution function for QUIT data data */
.fi
these changes are needed in order to support analogous
changes to fbuttons and mbuttons
.ip \fIget_genhd_coded\fR
A bug was fixed in the library function
\fIget_genhd_coded\fR for
items with more than one element, the returned value consisted of
repetitions of the first element.
.ip \fImatinv\fR 
a bug in the determinant functions, \fIdeterm\fR and
\fIdeterm_d\fR was
fixed: they would allocate memory and not free it before returning.
The problem was apparent in the operation of the \fIclassify\fR program,
which would fail with a memory allocation failure after classifying
some number of records (a number depending on the number of classes
and the number of features used for classification).
.ip \fIread_header\fR
a bug was fixed that could cause a program to
fail when reading a FEA_SPEC file with frequency format ARB_FIXED by 
unnecessarily demanding the presence of a \fIsf\fR generic header item.
\fIread_header\fR was also modified to handle version 1.7a of Sphere
headers.
.ip \fIwaves_show_sd\fR
this new library function allows user to
display an array of data by
a simple call and have the result displayed in an xwaves window if
xwaves is running in server mode.
.sh 1 "THE PUB DIRECTORY" 
.lp
The directory $ESPS_BASE/pub contains full-source copies of 
certain relevant and useful public domain programs. You are 
free to use them and pass them on in any manner consistent with 
restrictions stated by their authors.  This release 
contains these programs:
.ip \fIghostscript\fR
This is a GNU implementation of PostScript.   It can be used to display 
PostScript files on the screen for certain PostScript translations.  We have 
included it to make the script \fIps2epsi\fR available.  This script (which 
uses \fIghostscript\fR will take the PostScript file from the new print
option on \fIxwaves\fR and \fIplot3d\fR and generate a new file including a
preview image.  This allows a low resolution image of the PostScript file to
be shown on the screen when the file is imported into programs such as 
FrameMaker.    
.ip \fItpipe\fP
This is a utility that splits a \fIunix\fP pipeline into two
pipelines.  Stated differently, the output of one pipe can provide the
intput to two others.  \fItpipe\fP was written by David B. Rosen of
Boston University.
.ip \fIxgrabsc\fP
A utility that allows you to grab arbitrary portions of the 
screen and output them in Postscript or many other formats.
\fIxgrabsc\fP was written by Bruce Schuchardt.  
.ip \fItek2ps\fR
Written by Michael Fischbein, this program converts tektronix graphics
codes into Postscript.  This is used by some of our plotting programs.
.ip \fIshellforms\fP
This is a utility to build and edit forms.  It was written by
Paul Lew.
.ip \fIghostscript\fR
This is a GNU implementation of PostScript.  It is included here because it 
includes a script that can process a PostScript file as output by the new print 
graphics feature of ESPS and \fIxwaves\fR and add a preview image.  This
script is \fIps2epsi\fR.   The particular version of this script in our bin
directory has been modified to refer the the \fIghostscript\fR library
in our pub directory.   If you desire to use the general features of 
\fIghostscript\fR, you will have to install it from the source.
